WILLIAM HORACE IfIOOPER, OF ANGELS CAMP, CALIFORNIA.

CLEANING-ROLLER FOR ORE-CONCENTRATORS.

SPECIFICATION' forming part of Letters Patent No. 567,140, dated September 8, 1896.

Application filed April 9, 1896. Serial No. 586,843. (No model.)

To all whom it may concern:

Be it known that I, W1LLIAM HORACE IIOOPER, a citizen of the United States, 4residing at Angels Camp, in the county of Calaveras and State of California, have invented certain new and useful Improvements in Cleaning-Rollers for Ore-Concentrators; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to improvements in ore-concentrators, and more particularly to a cleaning-roller operated by pressure on a traveling belt, and is an improvement upon the devices shown in an application for Letters Patent by me filed July 10, 1893, and serially numbered 480,072. b

My objects are to provide a stop or dam across the surface of such concentrator-belt, which can be applied to any belt-concentrator, and to provide means for causing such dam to follow any side shift of the belt, so as to constantly extend across its whole width.

rI`he following description is illustrated by the accompanying drawings, in which- Figure l is a side view of a part of a concentrator with a cleaning-roller and hangers in position supporting the roller against the traveling belt. Fig. 2 shows a horizontal front lview of the concentrator with the cleaningroller,hangers,and guide. Fig. 3 is a sectional view of one end of the cleaning-roller, showing the construction of the journal and box.

A represents a concentrator-belt with plain surface and flange on each edge.

B is the cleaning-roller.

C C are guides adj ustably secured by setscrews a a to the journals of the roller.

D D are the two slotted hangers that hold the cleaning-roller in position. 'Ihese hangers are held in place by the rod E, which passes through slots in said hangers, one of which is shown by b.

F F are the journals of the cleaning-rollers.

Cr G are iianges on the concentrator-belt.

II is a rod that connects the two hangers, and which, in connection with these hangersl D D and the rod E with the roller B, forms a swinging frame that allows the roller to be applied to the traveling belt at any angle.

In most concentrators or vannin g-machines it is the practice to remove concentrates by allowing them to settle after being discharged from an oscillating concentratorbelt running through a tank of water.

In my invention the cleaning-roller B, supported against the travelingbelt A, forms a dam or stop that causes the concentrates to drop from the roller into a receiving-tank I. The cleaning-roller 'is held in place against the belt by the hangers D D, in connection with the adjustable guides C C, against which the belt-iian ges bear. In attaching the guides set-screws are used, which allows them to be removed and shifted at will. These guides C C are attached to the journals ofthe roller at points far enough from the journal-boxes of the hangers to permit the roller to adjust itself transversely to any side shift of the travelingbelt. The guides C C, being in constant contact with the iianges G G on the belt A, hold the roller B in the same position on the belt, always extending completely across it.

When a wooden roller is used, the journals are fastened in the body of the roller by means of barbs on the journals, as shown Fig. 3.

Vhat I claim isl. In combination with a concentrator-belt and its roller, said belt being adapted to have lateral movement, of a cleaning-roller supported in contact with the belt to have lateral movement to correspond thereto, said roller having a guide adjustable on thebearing thereof to engage the edge of the belt and thus maintain its position in relation thereto.

2. In combination, the. belt with its rollers, the adjustable hangers D, the cleaningroller having its journals bearing in the ends of said hangers to have longitudinal movement therein and adjustable guides on the cleaning-roller engaging the edges of the belt to move the roller laterally with said belt, substantially as described.

In testimony whereof I have afxed my signature, in presence of two witnesses, this 29th day of February, 1896.

WILLIAM nonAcE HooPER.
